ASTM C1407 - 98(2011)e1 standard practice for calculating areas, volume, and linear change of refractory shapes

Fireclay steel-teeming nozzles and sleeves are classified by volume reheat change. Bloating of some refractories results in irregular reheat dimensions, which are difficult to measure. This practice determines the volume without depending upon physical linear measurements. Blast furnace checkers that have irregular cross-sections are classified by “creep properties.” This practice ...
